Fire fittings
Fire-fighting pipe fittings refer to the metal chain interface on the fire-fighting pipe belt. As a product made of a special material, its connection operation is very simple and does not require special professional skills. Ordinary workers can operate it through simple training. On the other hand, the performance and strength of fire-fighting pipe fittings are relatively high in terms of joint sealing, compressive resistance and so on.
1. At present, the fire trench pipe fittings produced in my country can be divided into two categories:
1. The pipe fittings that play the role of connection and sealing include rigid joints, flexible joints, mechanical tee and groove flanges;
2. The pipe fittings that play the role of connection and transition include elbow, tee, cross, reducer, blind plate, etc.
PS: The fire trench pipe fittings that play the role of connection and sealing are mainly composed of three parts: sealing rubber ring, clamp and locking bolt. The rubber sealing ring located on the inner layer is placed on the outside of the connected pipe, and is in line with the pre-rolled groove, and then a clamp is fastened on the outside of the rubber ring, and then fastened with two bolts. Due to the unique sealable structure design of the rubber sealing ring and the clamp, the groove connection has good sealing performance, and with the increase of the fluid pressure in the pipe, the sealing performance is correspondingly enhanced.
